Cottonmouth(2009) [The Bloated Ghost]: Dies (off-screen) of toxic shock syndrome, some time before the story begins; she appears as one of a group of ghosts who return to get revenge on John Brodie. (I haven't seen this short film, but I have read the original story on which it was based.)

The Lovecraft Chronicles: Dumas(2010) [Vampire Bride]: I don't know the circumstances of her death (though I'm assuming a stake through the heart), but her IMDB page includes a promotional photo of her death scene.
